I have had a cough for 8 weeks, ever since i had the flu. I have been to several doctors and twice to urgent care, struggling to breath. I have had a z- pack, a cortisome shot, steroids, an inhaler, breathing treatments, and two chest x-rays which were negative for pneumonia. I also have Parkinson s disease. Could the PD be the cause of this lingering bronchittus? Deborah YYYY@YYYY
